Science in the Courts - A Communication Problem

Subtitle: Also a Matter of What is Truth

Update 1: Third and final part of the article is published below. -- end update

A most interesting blog article appeared a few weeks ago at WUWT (see link), written by Dr. Tim Ball and titled "The Recent Senate Climate Hearing Failed Because It Continues To Miss The Point."  

The article was interesting for a few reasons, among them are 1) it is flat wrong on the position that courts will not hear scientific matter, and 2) it raises the issue of failure in communications between elected officials and the learned specialists (in this case, scientists).  

Both of these issues interest me, and with my background as both an attorney-at-law and a chemical engineer, these points deserve some discussion.   This SLB article is the start of that discussion, it may be added to from time to time.  The issues are deep, complex, and at times fairly fuzzy - that is, no sharp lines exist to define what is right or wrong, what is legal and not.   Each issue is discussed at some length, and a better strategy is offered for improving communication of complex issues. 

The climate realist world is fairly small (climate skeptic is another term for climate realist), and I don't pretend to know all the participants; I am certain they don't all know me.   But, for various reasons, I have managed to participate a bit, and meet a few, of the participants.  This is not a name-dropping exercise, though.   As to Dr. Tim Ball, I have not met the man but I have heard and seen him speak on climate matters, in summer of 2014 at a gathering of climate realists in the US.  

The two issues mentioned above are discussed next, in turn. 

Courts and Science

Dr. Ball states, “Courts will not listen to or judge scientific disputes.”   And a bit later, “. . . courts won’t consider scientific disputes.”   Some context on his statements is in order.  It appears that Dr. Ball is referring to his ". . . participat(ion) in appeals to the US Supreme Court over actions of the Environmental Protection Agency (EPA)."  (all quoted matter from the 12/19/2015 WUWT article linked above).  Dr. Ball also references three defamation lawsuits where science was not allowed as an issue, to the best of my knowledge.  

It is not true that courts will not consider scientific disputes; stated more affirmatively: courts will address scientific disputes at some times.  In the US, the court system is divided along several lines, one such line is state courts, and federal courts.  Other divisions also exist, such as criminal versus civil courts, and lower courts versus appellate courts.   In general, the lower courts (both criminal and civil) address matters of fact, and matters of law.  To non-lawyers, those statements seem clear but likely are not fully appreciated as to their meanings.   More on that later.   In the appellate courts, matters of fact are heard on very rare occasions, while matters of law are the primary issue.  

A matter of fact is one in which some item of evidence is presented to a jury (or a judge in a bench trial) for the jury to decide if the fact, as presented, is true or not.  There may be some doubt as to the truth of the matter, which is familiar in the standard of proof that is required to convict an accused person in a criminal matter: he must be found guilty beyond a reasonable doubt.   It should be noted that scientific disputes occur both in criminal and civil cases.  In criminal cases, typical science disputes may occur over things such as ballistics for bullets, toxicology for cause of death, and others.  In civil cases, science disputes may arise over things such as measurement of air or water pollutants, or the causes of a consumer product that malfunctioned and led to personal injury or death.  

A matter of law is different from a matter of fact; a matter of law is concerned with whether or not an issue is something that a court will decide, and if it can decide, what law is to be applied to it.  Typical examples are to determine if a matter concerns the law of contract, or tort, or property, criminal law, Constitutional law, procedural law, evidence law, consumer rights, elder law, family law, and a host of others.  

The US Environmental Protection Agency (EPA) has legions of attorneys that both defend, and prosecute, lawsuits based on science disputes, such as the toxicity of various chemicals on humans, plants, and animals.  One need only perform an internet search on a term such as "lawsuit and EPA" to find literally millions of sites that meet those two criteria. (a recent search returned 6.7 million hits).    Or, one can visit the EPA's own website http://cfpub.epa.gov/enforcement/cases/ to see literally hundreds of lawsuits  (click on the link to visit that page).   Note, not all the lawsuits involve science, as some involve procedural matters.    

The US EPA is not alone, as state environmental agencies and local agencies also employ armies of attorneys for similar purposes: prosecuting and defending against lawsuits.  As the head of a local Southern California environmental agency said to me in one of our meetings, "We cannot win.  Some parties sue us because we are doing too much, while others sue us because we are not doing enough."  

Courts also have standards for how to handle scientific testimony, or offered evidence of scientific matters.  While there are hundreds of references on this, one that has a good discussion is from the 160-page Roscoe Pound Foundation 1997 report, "www.poundinstitute.org/sites/default/files/docs/1997ForumReport.pdf."   see link.  Federal courts are required to use the Daubert standard, while state courts may use something similar.   Essentially, the evidence that is offered must be "good science" and not "junk science."   How to determine what is "good" and what is "junk" is the purpose of the Daubert standard.  

The Daubert standard has 5 parts:  

(1) whether the theory or technique in question can be and has been tested; 
(2) whether it has been subjected to peer review and publication; 
(3) its known or potential error rate; 
(4) the existence and maintenance of standards controlling its operation; and 
(5) whether it has attracted widespread acceptance within a relevant scientific community.

A court requires each of the Daubert 5 parts to be presented and argued before the judge, and accepted, before the evidence is allowed to be presented to a jury.   

State courts, though, are free to use different standards.   Some use the Frye standard, while others use the Daubert standard.  The Frye standard requires the court to determine whether or not the method by which that evidence was obtained was generally accepted by experts in the particular field in which it belongs. 

A final word about science being heard in the courts: appellate courts, as mentioned above, generally do not decide issues of fact.  They typically decide issues of law.  However, on some occasions, an appellate court uses a standard of review known as de novo, and will consider the issues of fact.   At the US Supreme Court, as Dr. Ball mentioned in his article, issues of fact are very rare.  

The fluid nature of science is also a very great concern in a court, as judges and most attorneys know quite well that scientists frequently and sometimes loudly announce that what was formerly considered "settled science" has been refuted or overturned or substantially changed by new findings.  This is especially true in what is generously referred to as health science, where different foods or liquids are found to be bad for humans in one study, then found to be beneficial in later studies.  Interested readers are encouraged to look into the health effects (or harm) from coffee, wine, chocolates, dairy products, eggs, and sugar, to name but a few.  

In the climate science field, it is also a known fact that climate scientists make bold pronouncements from time to time, then change that completely only a few years later.  One specific example of this is the continued, and often-repeated, adjustments to the average global temperature anomaly, such that the past gets colder with each new version, and the warming trend gets greater and greater.   

One of the most laughable of all climate science claims is that "the science is settled."    I had a little fun with that a few years back on SLB, see link to "Climate Science is Not Settled," with a compilation of "settled science" and my commentary on each.  I hope the reader enjoys those.  

This leads to another complaint Dr. Ball makes, “The basic argument is that it is “your paper” against “their paper” and they (the courts) are not qualified to judge.”    It is quite true that a court case boils down, many times, to one expert's testimony against the testimony of the other side's expert.  However, and here is where Dr. Ball is quite wrong, it is not the judge who makes the decision to not hear the case where there are battling experts.  This is an argument that an attorney makes when counseling his client about the prospects of success or failure in litigation.  The attorney knows that a trial will come down to the jury, or in some cases a judge, hearing two expert witnesses testify where one says that his conclusion, “their paper,” is correct, whereas the other expert says that his conclusion, “your paper,” is correct.   A jury or judge is typically not trained or experienced in the science and cannot make sense out of either expert’s argument.   However, as noted above, trials do occur and expert witnesses do testify before juries and judges

Communication Failure Between Elected Officials and Learned Specialists

Dr. Ball writes, “The same problems confront any discussion in a formal hearing about climate science. Politicians are no better equipped or qualified to determine a science confrontation than the Courts.”  

This is partially true.  As described above, the courts routinely hear matters in which science plays a significant role.   However, it is true that most politicians have a poor understanding of science.   Politicians are generally not scientists nor engineers, as many are attorneys with non-science and non-technical backgrounds.   These elected officials generally rely on staffs of experts, or paid consultants, to provide information and summarize arguments for and against an issue.   However, elected officials also hold hearings, usually public hearings, so that interested parties (sometimes known as "stakeholders") can present their views.  

As shown above, science has conflicting claims in many areas, which are well-known to elected officials.  It is difficult for the elected officials to know which claims to believe, which scientists to believe, and how far to believe them if at all.   


Temperature record of Abilene, Texas from 1886 showing very cold winters 1977-78-79
A short digression for some examples of climate science having poor credibility: Forty years ago, in the late 1970s, the public was bombarded with stories of global cooling.  The winters of 1977, 1978, and 1979 were unusually cold and harsh (where the winter is defined as December of the previous year, and January and February of the year shown by the date; that is, Winter of 1977 includes December of '76 through February of '77).   See adjacent graph for the temperature range, by year, for Abilene, Texas.   Note the three small dips at the lower portion of the graph and just above the 1980 mark on the X axis.  These three dips reflect the very cold winters.  Note also that at no other time in the entire record of more than 100 years, did three winters occur with such severity and in succession.  Those three winters were unique in the entire record.     Note also that this was not limited to Abilene; many other areas across the US were similarly impacted.  Interested readers can read more at this link.   (The article is titled: "Illinois Third Consecutive Severe Winter: 1978-1979,"  and has graphic descriptions with measured data on the severity of the three subject winters.) 


Yet, today, the global cooling stories from 40 years ago are pushed aside, and the new alarm is over global warming.   In addition, the climate alarmism is published every few years by the IPCC, the Intergovernmental Panel for Climate Change, yet their conclusions change each year.   Also, the global average temperature anomaly, which climate scientists produce from time to time, has frequent changes that almost always produce a warming trend that becomes greater each time the scientists change it.   Next, the climate scientists have a great many computer models of the global average temperature anomaly, but their models not only do not agree with each other, but do not match the measured temperatures either.  The lack of agreement between the models and measurements has been given a popular name, "The Pause," due to the cessation of increase in measured temperatures.   Finally, and perhaps most ominously, almost every prediction made by the climate scientists has failed to occur: Arctic ice disappearing, continued warming (as just mentioned), more hurricanes or tropical cyclones, a hot spot in the atmosphere, accelerated rise in sea levels, disappearance of snow, droughts and floods of unprecedented length and severity, and many more.   None of these predictions came to pass.  

Therefore, if one is an elected official and climate scientists are summoned to a public hearing to convey their scientific findings, what is one to believe?   How can a climate scientist possibly communicate effectively and persuade the elected official that any scientific finding or conclusion is true?   It matters not, or very little, which side the scientist is on, the global warming alarmism side, or the skeptic side that holds that any warming that may be occurring is not only negligible but is due to man-made, artificial adjustments to the temperature record.  The elected official does not know who to believe, because the track record, the credibility, of climate scientists is indeed dismal.  

The Battle Between the Papers

Next, Dr. Ball states, “They (skeptics) must show how “Their paper” (warmists’) was deliberately falsified in terms the public can understand. The recent US Senate hearings failed because the “Deniers” (skeptics) explained the scientific problems with the science of “Their Paper” (the warmists' paper).  The politicians and public didn’t understand the difference. Even if they entertained the idea that “Their Paper” was wrong they were confronted with the question of whether the errors were from incompetence or corruption, something the presenters of “Your Paper” (skeptics)  were not able or willing to answer.”

The battle between competing experts, or in this case, climate scientists who testify at a Senate hearing, very likely does result in utter confusion by those who listen to the experts.  Dr. Ball raises the interesting question of Why are the Warmists wrong?  He suggests that incompetence or corruption may be the culprits, yet the skeptic scientists were not able or willing to make those charges.   Such charges are indeed serious, as incompetence at one's profession, if false, is grounds for a slander or libel suit in defamation.   A charge of corruption, perhaps deliberately falsifying data to obtain an agenda-driven conclusion, is also very serious.  Such a charge, if true, can carry criminal penalties for fraud, and civil penalties for damages.  

Part of the problem is, of course, that the data - the basic, original data - that underlies much of the controversy is either missing, or hidden from view by claims of contractual obligations, confidentiality, or exemptions of some form from Freedom Of Information laws.   It is indeed difficult to make a valid charge of corruption when one cannot know what actual changes were made to the data.  

Yet, there are effective ways to show politicians, and other interested but non-technical observers, not only that the Warmists' papers (and positions) are wrong, but why.  That subject is addressed in the next section. 


Communicating Complex Issues

Effectively communicating a complex issue is a very common, even ubiquitous problem in the legal setting and in many non-legal settings.  How does one effectively communicate a complex issue, and persuade or convince a person or group (perhaps senators at a hearing, a patient with a serious medical problem, or a jury deciding a trial's outcome, or even a room full of conference attendees) that a particular position is correct, and the other side is wrong?   

First, examined below is what attorneys do in trials to win their case when a jury of ordinary people will decide the outcome.  Second, how experts are chosen and directed by the attorneys.  Yes, the word is directed, just as a movie director directs the actors in a film.  Third, what scientists can do to improve their communication and persuasive skills.   The third part is further anayzed by the concepts of Who, How, and What.  

Can Scientists Learn Anything from Trial Attorneys?

If one were to judge from the harsh treatment afforded those intrepid attorneys who venture into blog discussions on climate change, no one is listening to an attorney.  Attorneys are (almost always) vilified, scorned, and ridiculed as know-nothings or worse.   However, recognizing that at least some attorneys are good fellows (and ladies) who are knowledgeable, bright, experienced, and act ethically while still advocating strongly for their client, there are some good lessons to be learned from attorneys on effective communication of complex issues. 

The first lesson from the attorneys is that juries, as intelligent people but untrained in a technical or complex scientific matter, normally make their decisions on factors other than the complex "stuff."  They tend to decide on things like who was more believable, who was nicer, who was more attractive, and who seemed more trustworthy.   As stated by law Professor Joseph Sanders, 

"As for juries, we have indications that they have trouble with complex cases, and with scientific evidence, and we have reason to believe that better-educated juries do better in these areas. We have indications that juries approach expertise with skepticism. We have indications that juries appraise expert testimony not by grappling with technical issues, but by counting extraneous factors like qualifications, the number of arguments (rather than quality), and personal attractiveness. We understand that jurors give more credence to
messages framed in simple language, less to those framed in complex language, and they pay close attention to demeanor. "

Therefore, winning arguments will include the complex issues, no doubt, but those arguments will also be delivered in a manner designed to maximize the impact on the jury.   The language used, the message, will have an easy-to-understand overview.  

To make a point memorable, or even to summarize the case, attorneys sometimes invent a short phrase to repeat to the jury, something memorable, perhaps a rhyming couplet.  An example follows from the famous OJ Simpson murder trial, pertaining to the gloves.  The attorney said, “If it doesn’t fit, you must acquit.”   That is short, and it rhymes.  This refers to the glove that the murderer supposedly wore, and if it did not fit OJ Simpson, the accused, then the jury was to acquit, find him not guilty.    

Another famous trial had a different rhyming couplet that was stated to the jury multiple times:  “If the lion gets away, Kerr-McGee has to pay.”  This was from the case of plutonium radiation poisoning in the Karen Silkwood case.   The attorney was trying to emphasize the legal point of strict liability, for ultra-hazardous materials such as the plutonium at issue in the case.  In strict liability, no matter what happens that allows the harm to occur, the defendant must pay.   Here, “the lion” refers to an ancient case in which a defendant owned a lion that escaped its cage, then attacked and injured the plaintiff.   Plutonium in the Silkwood case was an analogy of the lion.   The attorneys alleged that improper safeguards by Kerr-McGee allowed plutonium to escape and contaminate Ms. Silkwood.    

A critic might say, this creating a simple rhyme is grandstanding.  This has no place in a serious discussion or debate about something as vital to human survival as global warming.   And perhaps the critic is correct.  Or, perhaps what is needed is a memorable phrase that catches the public's attention and draws more scrutiny of the underlying arguments, both for and against the conclusion.   Perhaps the warmists can chant, "We are all going to die, from CO2 in the sky."  Where CO2 is spelled out C-O-2.   Or another version, "Too much Carbon in the Sky, We are all going to die."    The variations are endless, and can be a bit amusing. 

In addition to creating a catch-phrase, the attorney must select a good expert witness and develop the expert's testimony.  

Choosing Experts and Directing Them 

Ideally, an expert witness has characteristics that the jury finds him (or her) believable, and likeable.   Important characteristics are the expert's appearance such as clothing and shoes, speaking voice, mannerisms, demeanor, authoritative (education, degrees, society memberships, publications, honors, experience, whether a teacher or professor, and how often called to testify as an expert).   The ideal expert is especially cool when cross-examined, when challenged, when shown to be wrong.
  
Attorneys choose their experts wisely.  They go over and over the testimony, with special attention to word choices, voice inflection, mannerisms, and how to remain cool under duress.  They will rehearse the use of visual and audio aids, posters, charts, exhibits, physical models, and other ways to clearly make a point.    Some types of sentences are difficult to understand, while others are much easier.   The vocabulary may be unfamiliar to the jury, so some time must be allocated to explaining what the various terms mean.  

The attorney not only presents his own side through having the expert testify as answers to various questions, but he will also negate, or undermine, the other side's evidence.   It is helpful to show where the other side is wrong, or to show that there is uncertainty, even substantial doubt or inaccuracy. 

The climate scientists can do similar things to improve their communication. 

Scientists As Communicators and Persuaders  

It is certainly true that not all scientists who want to communicate in hearings, and persuade the panel, are tall, tanned, athletic, good-looking, have a full head of neatly groomed hair, and a pleasant but resonant voice.   Or, if a female, the feminine equivalent.   Yet, there are things that can be done, and must be done to improve communication.  The scientist as testifying expert can wear nice but not gaudy clothes, new and shined shoes, and have hair trimmed neatly.   It is perhaps not proper, but juries notice things like fingernails, so those too must be trimmed and clean.   

A communication specialist, or an experienced trial attorney, can be engaged to listen to the scientist's presentation and offer improvements.   There is an art to public speaking, to making a presentation that is understandable, even to the choice of graphic design and colors.   (SLB has a few instances where poor visual aids were used in public presentations by various scientists.  One word of advice:  yellow in a graph is not a good idea.)    

The speaking voice almost always can be improved with coaching and practice, to one that is easy on the ears, smooth and not harsh or distracting.   It can be humbling for a speaker to go through such coaching and criticism.    Eliminating annoying habits takes more coaching and time, but a good message effectively delivered can be destroyed by a momentary lapse of good etiquette.   One can learn and practice the conventional parts of speech that make for good listening, such as introductions, transitions, and concluding phrases.  

The scientist likely already has an impressive resumé with academic degrees and a publication list, perhaps even a position as a professor.   There may already be society memberships, and perhaps honors from that or other societies.   Such things impress a jury, or a panel of senators.  

Now, with the Who and How having been somewhat discussed, the What of the presentation is given.  

What, exactly, can a climate scientist discuss to make his or her point effectively and memorably?   How is one to win, when both experts are equally believable, calm, cool, collected, well-dressed and groomed, authoritative, well-spoken, and dignified?   

One way is to undermine the other side by showing that if the other side is right, certain outcomes that should be true are actually not true.    Conversely, the scientist can bolster his side by showing that if he is right, certain outcomes that should be true actually are true.   Examples of warmist claims that have not occurred, as discussed earlier, include Arctic ice disappearing, continued warming, more hurricanes or tropical cyclones, a hot spot in the atmosphere, accelerated rise in sea levels, disappearance of snow, droughts and floods of unprecedented length and severity, and many more.  

The skeptics have evidence that is persuasive, such as a general pause or cooling of the atmosphere while the sunspots are in a very weak cycle, fresh-water lakes having more persistent ice, and perhaps the most persuasive argument of all, the adjacent cities problem.   One of the central pillars of science is that science is consistent, it is not arbitrary.  What works in one location also works in all others.   In my speeches on this, I use the example of gravity is very consistent around the world.  Engineers depend on this to build our machines and infrastructure.  Yet, the world of climate science has the same CO2 concentration above adjacent cities, but one city warms while the other does not.  Or, one city cools while the other does not.   This very fact is essentially proof-positive that CO2 in the atmosphere can not be causing a global warming.  

There is also the very persuasive, but complicated, concept of CO2 and warming as a violation of process control principles.   That one takes a fair amount of explaining, as I have done earlier on SLB.  (see link to "Chemical Engineer Takes On Global Warming," which is in the top two most viewed articles on SLB.)

A persuasive argument can also undermine the other side by showing the methodology is flawed.  In climate science's atmospheric temperature data, there is over-inclusion of temperature data from cities and other UHI influences, making adjustments to data, making up data, splicing data, adding in new records of shorter length, and many more.   There also is the model variable problem, or omitted variables.   Models do not account for clouds as albedo increases, nor for sunspots and cloud relationships, nor for windy versus calm days, nor for many other variables.  

Perhaps the most persuasive argument for the skeptic side, though, is one that was made here recently on SLB.   The problem with the warmists' approach and conclusion is the inclusion in their temperature data of any location that has a human influence, such as data from cities.   The fact is, and quoting from the SLB article from November 2015, "even if all the electricity (and other energy) is from a zero-carbon-dioxide source, the cities would still have UHI and would corrupt the climate scientists' data."    The full quote:

". . .cities will have energy consumption and heat rejection issues no matter what type of system produces that energy.  Considering for the moment electricity use, even if a city were all-electric for heating, cooking, and transportation, and even if that electricity were produced by zero-carbon-dioxide power plants (see below), the UHI would exist.  In essence, a building has no idea what produced the electricity that heats the building, runs the lights and elevators, and heats the hot water.  An electric car, or bus, or delivery truck, or train, also has no idea what produced the electricity that each of those consumes.   Therefore, even if all the electricity is from a zero-carbon-dioxide source, the cities would still have UHI and would corrupt the climate scientists' data.   Such zero-carbon-dioxide sources include, but are not limited to, hydroelectric, wind, solar, nuclear, geothermal, wave, tidal, ocean current, ocean temperature-difference, water pressure recapture, river mouth osmosis, and river current.   There are also carbon-neutral sources: landfill methane, cattle operation methane, Municipal solid waste (MSW), human waste sludge, plant-based ethanol, and other bio-fuels.  


It is entirely wrong for climate scientists to include any data that is corrupted by UHI."   see link

Therefore, and again as argued here on SLB, it is critical to use long-term temperature records for trends only from pristine locations, from very low-population areas.   see link

When one considers, as Dr. Ball did, whether to make a charge of deliberately falsifying the "paper," or evidence of warming, or make a charge of incompetence, or even corruption, it is likely only necessary to show that the wrong data was used to establish a warming trend.   It is wrong to use data from populated areas, as those areas would have warmed, and will continue to warm, even if all the power on the planet was from hydroelectric dams.    In fact, it could be shown, if we had the temperature records, that cities were warmer than farms even 200 or 500 years ago.  


J. Goodridge. 
To close, once again the Goodridge chart is shown, where almost 100 years of temperature trends are classified by population in a county.  Warming was absent in the counties with very low populations, yet a pronounced warming trend exists for counties with large populations.   As shown above, CO2 in the atmosphere cannot possibly be that smart, to recognize that a city is below it and zap the city with its heat-increasing rays.  But, to know when a farming area is below and to holster its heat-zapping gun. 

In conclusion, scientists who want to communicate complex issues to non-scientist audiences could benefit from collaboration with trial attorneys.   While a panel of elected officials, perhaps Senators, is not the same as a panel of jurors, and a Senate hearing is much different in rules and duration from a jury trial, there are similar things that can be done to improve communication.

Knowing versus Not Knowing

Subtitle: Ignorance is no substitute for knowledge

The search for Truth - with a capital T - has a long history.  How do we define something as True?  In part, the answer lies in what that something is.  Easily verifiable statements are true, if the verification is positive.  For example, it is true to state that the Pacific Ocean lies to the west of North America.  At the other extreme, truth is elusive for highly subjective statements such as "my dog is cute."  The dog may be cute to some observers, but very ugly to other observers.   Another consideration is the iceberg principle: what may appear to be true (no danger to a ship from the small top of the iceberg) is not true when all the facts are known (the underwater, hidden, and huge part of the iceberg is a danger to a ship).  In a court of law, judicial notice is taken when neither party wishes to dispute the truth of a fact that has some bearing on the case.  The fact is taken as absolutely true, with no doubt associated with that fact.  An example of a true fact, one that would have judicial notice in a court proceeding, is that June 27, 2015, is a Saturday. 

Note, there are some who quibble and object that islands are part of North America and are surrounded by the Pacific Ocean.  An example is Santa Catalina Island, offshore southern California.  

Background - about me and why I write this article
For those who may be new to Sowell's Law Blog, SLB, I am both an attorney-at-law and have long experience in chemical engineering in a great number of process plants around the world.  In addition to my law practice, I write on a number of topics, and make speeches to various groups from college students to professional engineering societies.    SLB topics typically include climate change, nuclear power, renewable energy, fossil fuel energy, government regulatory issues, fresh water, NASA's missions, engineering and scientific professional liability, Free Speech and the First Amendment, especially defamation, and others.   My stance generates some responses, of which quite a few are positive and some downright nasty and negative.   A few commenters, who sometimes send email, resort to vicious personal attacks, character assassination, and libel.   

For some perspective, SLB has existed since March, 2008, and has received almost 120,000 pageviews from more than 40,000 unique visitors in 140 countries.  At this time, there are 280 posts, and the blog receives approximately 3,000 views per month.  (Those statistics are not especially notable in the internet world, yet they are what this blog has produced over its 7 year life.  This represents far more views, and far more visitors, and certainly far more countries than I ever envisioned.  Alexa's global rank for SLB is 21.4 million, out of more than 1 billion websites globally).  

What sometimes puzzles me is how so many people, typically those with nasty and negative comments, can hold the positions they hold.  This article explores some of the reasons people hold an opinion. 

Knowledge Matrix

A knowledge matrix is a binary matrix with two parameters, with each parameter taking one of two values.  The two parameters are 1) knowledge a person can have, and 2) the realization the person has of having the knowledge.   The two values for each parameter are yes, and no, as shown below.  

  A) Don't know but don't realize it
  B) Don't know but do realize it
  C) Do know but don't realize it
  D) Do know and do realize it

For A) a person doesn't know the knowledge but also does not realize he doesn't know.  This person is (probably) blissfully ignorant of that particular bit of knowledge.  Experience has shown that many people, perhaps most people, have this A) condition for a great many subjects.  As examples, an unpublished bit of scientific knowledge may have only a few people who know about it, while the rest of the world population don't know and don't realize the knowledge exists.  Also, social groups that are isolated have no knowledge of events outside their local area and may not realize the outside areas exist.  

For B) a person doesn't know the knowledge but realizes he doesn't know. This person is one who recognizes that such knowledge exists, but realizes that he himself does not know the knowledge.  For example, most of us (excluding medical doctors) are in this category with respect to deep medical knowledge.  We know that a vast medical knowledge exists, and we may actually know some of it, but we realize we don't know all that a trained medical doctor knows.   This also describes a person with a shallow knowledge of any subject, who realizes that a complex and deep body of knowledge on that subject also exists.  

For C) a person does know the knowledge but doesn't realize he knows it.  This may seem a bit unrealistic, since most of us are aware of what we know.  Yet, examples exist all around.  A shy person may have never made a speech in public, but once he tries public speaking and has success, he enjoys public speaking.  He had the knowledge of how to speak in public but did not realize it. 

Finally, for D) a person does know the knowledge and realizes he knows it.  This describes people who have studied a subject, or practiced activities until they are proficient.  

This becomes important, the A B C D categories, when matters of some public concern are discussed.  Especially with the internet and its literally millions of websites, it can be seen that writers (and speakers) from all categories are publishing their views.  But, pre-internet, similar situations existed with traditional print and broadcast media.  People who wildly speculate might be in A), they don't know and don't realize they don't know, but they write very wrong things.  People in B) may write, but acknowledge they don't know and therefore seek opinions from authorities and quote those authorities.  That in itself has problems, discussed later.  People in C) may write, although in my experience those are rare.  They know, but don't realize they know, so they don't write.   People in D) may write, those who know and realize they know, and have valid points.  

However, the A B C and D categories are not sufficient; what about those Ds who know, and realize it, but deliberately omit key facts or distort the facts, or outright lie, to further their agenda?  This has great application in several key areas discussed below. 

Furthermore, what about those who don't know and don't realize it, (A), but actually believe they do know and realize it?  They may trust authorities, and repeat the talking points.   These may be good, honest people, but they simply have never heard the opposing viewpoint.  (e.g. people who don't know that the climate scientists adjusted historical data, omitted variables in their models, ignore important correlations, include data that should be excluded as invalid) (e.g. in nuclear power, those who never have heard the safety, costs, or subsidy facts such as shown by TANP series) (e.g. renewable energy costs are rapidly declining, with increased production and grid penetration with no ill effects, storage is solved with MIT underwater storage) (e.g. fresh water is abundant but in the wrong places and the wrong times in floods, need transfer systems such as NEWTAP, or dams and reservoirs).

Tests for Veracity and Acceptance - Daubert Standard 

How, then, can one determine the truth of what people write?  The example of a court trial is given.  In US Federal Courts, and some state courts, an expert witness' testimony is tested to determine if the expert's reasoning and methodology is scientifically valid and can be properly applied to the facts at issue in the case.  The Daubert Standard has five parts:

(1) whether the theory or technique in question can be and has been tested; 
(2) whether it has been subjected to peer review and publication; 
(3) its known or potential error rate; 
(4) the existence and maintenance of standards controlling its operation; and 
(5) whether it has attracted widespread acceptance within a relevant scientific community.


Of course, almost none of what is written on the internet ends up in a Daubert analysis for validity.   Courts require the attorneys to prepare and submit arguments based on existing cases and a few other legal authorities.   Internet websites and blogs can function to influence public opinion, and individual opinions.  It is likely not necessary to run through the entire Daubert five steps, but an opinion that can pass all five steps certainly should carry some weight.    

What is interesting is how some people refuse to modify their opinions, even when faced with overwhelming proof that their opinion does not match the facts.   In some of my speeches, especially those to college engineering students, the audience members have not heard or been exposed to certain aspects of science and engineering.  It is an indictment of the primary and secondary school system that tries to indoctrinate the students with half-truths or outright false statements.   

For example, a student asked me years ago to read the environmental science textbook for a class he was taking, and comment on it.  I found it to be full of false statements, and very misleading where it had an element of truth.  The writer clearly had an agenda, and that agenda did not include the most good for the least cost.  One of the greatest false statements in environmental propaganda is that the Earth cannot heal itself.  One huge example is oil spills in the oceans.  The fact is that oil is a natural substance and has leaked into the oceans in very many locations around the world, and has done so for thousands if not millions of years.  Oil becomes part of the food chain in the oceans.  (one need only look up underwater volcanoes)  

Other tests for validity exist for an argument, with the several well-known false arguments from logic.  These include the appeals to authority, to heaven, to pity, and to tradition, arguments from consequences, ignorance, inertia, and from motives, the argument by force, by silence, the bandwagon argument, circular reasoning, the Big Lie, blind loyalty, the Ad Hominem (attacking the person), favoritism, bribery, complex question, the half-truth, lying with statistics, the non-sequitur or Red Herring, straw man, slippery slope, with more than 50 such fallacies listed here.   Many of these false arguments occur routinely in legal proceedings, in testimony, in depositions, in expert witness opinions, in attorney's summations, and at times, in judicial opinions.  It is important to identify the false arguments and refute them where possible. 

In matters concerning science and engineering, the data itself is subject to review, criticism, and many times, rejection.   A brief excursion follows, to describe what many people (apparently) do not know, or if they know, refuse to admit when discussing important topics. 

How Valid Is The Data

It is sometimes stated that all data has measurement errors, the only question is how big are the errors.  That is almost always true, but not quite.  Where one can have absolute accuracy is in certain data involving integers, or discrete objects.  One can, for example, count the number of chairs in a room, provided there is sufficient time to do the counting, the room is not overly large, and the number of chairs does not change during the counting.   For an ordinary room such as a banquet room in a hotel, one can quickly and accurately count the chairs.   One can also count the number of coins in a cash register.  (counting coins can be made much faster and more accurate by placing the coins in piles of ten, then counting the number of piles and multiplying by ten).   However, where a discrete number of things is not the object, measurements actually do have some error.   

Errors exist in most data, but where the errors are sufficiently small, the end-user does not care.  Sometimes, measurement errors are random and tend to cancel out over enough time.   At times, statistical methods are used to determine if the measurement is within the usual (historical) range of error, perhaps one or two standard deviations.   If the measurement is outside that range, notice is taken and the measuring device may be examined for recalibration or repair. 

Topical Examples

Having now examined some aspects of what people know, if they realize what they know, writers with agendas, validity of arguments, fallacious arguments, and accuracy of data, specific topics are examined.   These include, in no particular order, nuclear power plants, climate change and its prevention, mitigation, or adaptation, renewable energy systems, and abundant fresh water.   Each of these has appeared in articles on SLB, and each has attracted comments both positive and negative.  

Nuclear Power Plants

The subject of nuclear power plants, that provide electricity, is immense with almost limitless individual topics.  The fuel itself has many aspects, whether uranium, thorium, or fusion.  The reactor design has many systems from which to choose, from boiling water, pressurized water, advanced boiling water, molten fluoride salts, radioactive spheres, small, medium, or very large capacity.  The power generation scheme has different aspects, from steam, to circulating helium, and supercritical carbon dioxide.   However, even within the arena of existing licensed technologies, the boiling water reactor using steam to drive a turbine-generator, great controversy exists.   

Many industry proponents write articles and offer comments on blogs that show they are blind to the many and serious negative aspects of nuclear power.  As my articles on Truth About Nuclear Power, TANP, show, economics, safety, and subsidies all are very negative.  Yet, when confronted with the truth, many proponents resort to name-calling.   Others resort to what I refer to as the "Yeah, but..." argument.   Some proponents actually insist that the current nuclear regulatory regime is too restrictive, and must be relaxed to allow the plants to compete economically.   One argument they make is to greatly increase the allowable nuclear radiation that can be routinely or episodically absorbed by humans.  In essence, they don't mind frying the populace from time to time in order to build more nuclear plants.  

What is very interesting is that TANP has very little original data, from me.  Instead, the articles are a compilation of known facts and valid statistics from a wide variety of sources.  As an example, the fact is that nuclear power produces only about 11 or 12 percent of the entire world's electricity, as published in several reputable sources.  The logical conclusion drawn and published in TANP is that nuclear power is not the safest and most economic power source, for after more than 50 years of mightily striving in the electrical generation marketplace, it remains only a minor player.   (Coal, natural gas, and hydroelectric all produce more kWh per year than does nuclear power).   This fact causes howls of indignation from the proponents, with their protests including over-regulation, lawsuits from attorneys, public scare-mongering about safe radiation levels, and more.  

Another plain and simple fact of nuclear power is that no nuclear plant would ever be built, anywhere, if not for massive government subsidies and almost total indemnification from harm due to nuclear radiation releases.  TANP discusses this at length, based on irrefutable facts such as the Price-Anderson Act.   Nuclear proponents twist the facts around, by stating that the cost of insurance for a nuclear power plant is a tiny fraction of the power sales price.  That is actually true, but only because the Price-Anderson Act covers the liability and forces each nuclear plant to have a tiny amount of insurance.  

What, then, can be the motivation of the nuclear proponents to howl in such indignation, to resort to vicious name-calling when the facts are published?   As I have stated or questioned before, do they really want to permanently poison the planet with plutonium?   Or, do they have a naive faith in the ingenuity of future engineers to magically solve the huge technical problems that exist in nuclear power plants?   My answer to that one is, some of the best minds in history have applied their best efforts to making nuclear plants safe, reliable, and affordable, for more than 50 years.  The results speak for themselves - five massive reactor meltdowns in less than 40 years, near-misses every 3 weeks (in the US) even after decades of operating experience, huge construction costs that require government subsidies, very long construction times that typically last a decade or more, massive amounts of reserve power to take over when (not if) the nuclear plants trip off-line, and very expensive decommissioning.  With all that effort, nuclear plants produce only 11 to 12 percent of the world's electricity.   

It certainly appears that nuclear proponents, whether writing or making speeches, are a combination of the knowledge matrix types: some write even though they don't know themselves and parrot authorities, some write with an agenda to build the plants no matter what.   One of the best ways to argue and prevail is to omit the negative points and hope the opposition fails to mention them.  Nuclear proponents are masters of that line of argument.  Some proponents, apparently, have great faith in nuclear plant advances, but zero faith in other energy technologies.  (renewable energy is discussed below).
